Abstract

Disclosed related to a dust collector of a vacuum cleaner comprising a dust separation part separating dust from the air; a dust collecting body having a dust storage part storing the dust separated by the dust separation part; and a division part dividing an inner space of the dust separation part and the dust storage part, opening and closing the dust separation part selectively, and having an opening discharging the dust into the dust storage part.

Claims

1. A dust collector of a vacuum cleaner comprising:

a dust separation part separating dust from air;

a dust collecting body having a dust storage part storing the dust separated by the dust separation part; and

a division part dividing an inner space of the dust separation part and the dust storage part, opening and closing the dust separation part selectively, and having an opening discharging the dust into the dust storage part.

2. The dust collector according to claim 1, wherein the division part is rotatably coupled with the dust separation part.

3. The dust collector according to claim 1, wherein a hook is formed in the division part and an engagement end performing an engagement operation with the hook is formed at the dust storage part.

4. The dust collector according to claim 1, wherein the dust separation part includes a cyclone unit separating dust with operation of the cyclone, and a bottom part forming the bottom as extended horizontally from the cyclone unit.

5. The dust collector according to claim 4, wherein the upper part and the lower part of the cyclone unit are opened, and the lower part of the cyclone unit is covered by the division part selectively.

6. The dust collector according to claim 4, wherein the dust separation part includes a dust guide path discharging the separated dust toward the tangential direction from the cyclone unit, and leading the discharged dust to be discharged into the dust storage part.

7. The dust collector according to claim 1, further comprising a cover member selectively opening and closing the dust collecting body, and the dust separation part is fixed at the cover member.

8. The dust collector according to claim 7, further comprising a filter member arranged in the dust separation part and coupled with the cover member, and the filter member is able to be released from the cover member while opening the division part.

9. The dust collector according to claim 1, wherein the dust separation part is accommodated in the dust collector.

10. The dust collector according to claim 9, wherein a first guide part guiding the accommodation of the dust separation part is formed in the dust separation part, and a second guide part formed as corresponding to the first guide part and in which the first guide part is accommodated is formed at the dust collecting body.

11. A dust collector of a vacuum cleaner comprising:

a dust collecting body having a dust storage part;

a dust separation part accommodated in the dust collecting body, and separating dust from the air; and

a guide device guiding the accommodation of the dust separation part.

12. The dust collector according to claim 11, wherein the guide device including a first guide part protruded to outside of the dust separation part;

and a second guide part formed at the dust collecting body and accommodating the first guide part as formed to be corresponding to the first guide part.

13. The dust collector according to claim 12, wherein the cross section of the first guide unit is rounded.

14. The dust collector according to claim 11, wherein the dust storage part is divided into a first dust storage part and a second dust storage part, and the dust separation part is accommodated in the first dust storage part.

15. The dust collector according to claim 14, wherein the guide device includes a first guide part protruded at the first dust separation unit;

and a second guide part accommodating the first guide part as depressed toward the second dust storage part from the first dust storage part.

16. The dust collector according to claim 11, further comprising a cover member opening and closing the dust collecting body selectively as coupled with the dust separation part;

and

a filter member coupled with the cover member in the dust separation part, and the coupling of cover member and the dust collecting body is guided by the guide device.

17. The dust collector according to claim 16, wherein a division part opening and closing the inner space of the dust separation part selectively is arranged at the lower side of the dust separation part, and the exchange of the filter member is possible while opening the division part.

18. A dust collector of a vacuum cleaner comprising:

a dust collecting body having a dust storage part storing dust;

a dust separation part located inside of the dust collecting body, and separating dust from the air;

a division part dividing an inner space of the dust separation part and the dust storage part, and having an opening moving the separated dust to the dust storage part;

a cover member coupled with the dust separation part, and opening and closing the dust collecting body selectively; and

a filter member located inside of the dust separation part, and coupled with the cover member.

19. The dust collector according to claim 18, wherein the division part is rotatably coupled with the dust separation part.

20. The dust collector according to claim 18, wherein the dust separation part is accommodated in the dust collecting body selectively.

21. The dust collector according to claim 20, wherein a first guide part guiding the accommodation of the dust separation part is formed at the dust separation part, and a second guide part of a shape corresponding to the first guide part is formed at the dust collecting body.

22. The dust collector according to claim 18, wherein the dust separation part includes a cyclone unit separating the inhaled air with the operation of the cyclone, and the opening is located at the outside of the cyclone unit.

23. The dust collector according to claim 18, further comprising a fixed member fixed at the dust collecting body;

and a compressing member reducing the volume of the dust stored in the dust storage part due to the interaction with the fixed member as supplied to the dust collecting body as capable of rotated.

24. The dust collector according to claim 23, wherein the fixed member is located at the opposite side of the opening with the central axis of the dust collecting body as a standard.
